Counter Strike: Global Offensive has been given its first gameplay details.

The next iteration in the fan-favourite PC shooter will see cross-platform play between the PC, Mac and PlayStation 3 versions of the game, according to Kotaku.

The PlayStation 3 version will offer a variety of control schemes, from a standard controller to PlayStation Move as well as a mouse and keyboard.

Counter Strike: Global Offensive will feature seven classic maps, five for the Bomb/Defuse mode and the other two for Hostage Rescue, with each map receiving graphical upgrades while leaving level layouts intact.

Counter Strike: Global Offensive will be available on Xbox 360, PlayStation 3, PC and Mac in early 2012.
